[0027] This embodiment provides a vertical sealed tank negative pressure circulating water device, please refer to Figure 1-2 As shown, it includes a three-dimensional sealed tank 10, a water inlet pipe 20, an exhaust mechanism 30, a booster pump 40, a water outlet pipe 50, a control valve 60, a water wheel mechanism 70, a water reservoir 80, a generator 90, a transmission mechanism 100 and a reflux pump 110; the upper ends of the water inlet pipe 20 and the exhaust mechanism 30 are respectively connected to the upper part of the three-dimensional sealed tank 10; the booster pump 40 is connected to the water inlet pipe 20; the water outlet pipe 50 is connected to the upper end of the three-dimensional sealed tank 10 The control valve 60 is arranged at the lower part of the three-dimensional sealed tank 10 or the water outlet pipe 50; the water reservoir 80 is arranged below the water wheel mechanism 70; the generator 90 is connected to the rotating shaft of the water wheel mechanism 70; the reflux pump 110 is arranged in the water reservoir 80 and connected to the lower end of the water inlet pipe 20, and is connected to the rotating shaft of the water wheel mechanism 70 through the transmission mechanism 100.

[0028] Specifically, the device fills the three-dimensional sealed tank 10 with water through the booster pump 40 and exhausts the water through the exhaust mechanism 30. After the water is filled, the control valve 60 is opened, and the water wheel mechanism 70 is impacted through the water outlet pipe 50 to rotate, thereby driving the generator 90 to generate electricity, and the reflux pump 110 is driven by the transmission mechanism 100 to return the water to the three-dimensional sealed tank 10. At the same time, negative pressure is generated in the tank body during drainage to assist the water backflow through the siphon effect; when the water flow in the water outlet pipe 50 is small, the booster pump 40 can be opened to quickly catch up with the water flow; therefore, the device is used as a civilian power generation equipment; in addition, the water wheel mechanism 70 itself has sufficient volume and weight to generate a large inertia and maintain a long rotation time.

[0029] In this embodiment, the bottom of the three-dimensional sealed can 10 adopts a conical structure.

[0030] Specifically, the three-dimensional sealed tank 10 is set off the ground, and the water in the tank has a drop.

[0037] In this embodiment, a water overflow alarm 120 is further included, and the water overflow alarm 120 is arranged on the upper part of the three-dimensional sealed tank 10.

[0038] Specifically, the overflow alarm 120 includes a sensing probe and an alarm that extends into the tank; when the sensing probe senses water, the alarm is triggered through a controller to send an alarm signal.

[0039] In this embodiment, a one-way valve 130 is further included. The one-way valve 130 is disposed in the pipeline between the booster pump 40 and the reflux pump 110 .

[0040] Specifically, a one-way valve 130 is provided in the pipeline between the booster pump 40 and the reflux pump 110 to achieve normal water supply and prevent water from flowing back, while also maintaining a certain sealing effect.

[0041] In this embodiment, a starting mechanism 140 is further included, which is in transmission connection with the rotating shaft of the water wheel mechanism 70.
